Tandem cyclizations of benzopyranylidenetungsten(0) complexes with electron-rich dienes for the stereoselective synthesis of polycyclic carbon skeletons
o-Quinodimethanes, generated by the Diels-Alder reactions of benzopyranylidenetungsten(0) complexes with electron-rich dienes, further undergo intramolecular cyclizations to afford novel polycyclic compounds.
